Abstract

PURPOSE:To detect the face that chained parts are taker-up around a vacant winding reel, by determining a reference value based on the counted value of a counter at each period from the start of the driving of a sprocket to a specified time, and comparing the counted value of the counter after the specified time with said reference value. CONSTITUTION:A sprocket 3 is driven with an induction motor 6 from the start of the driving to a specified time during an initial period. The output pulses of an encoder 20 correspond to a circumferential speed v1 and an angular speed w1 of the sprocket 3. The maximum value Nmax of the counted values Ni of said output pulses in each period is automatically detected. A judging reference value Nt=betaNmax, which is required for detecting the finish of taking-up, is automatically operated based on the Nmax. The counted value A1, which is changed from time to time in each period in the taking-up step of the chained parts around a winding reel 5, is compared with the reference value Nt. When the value exceeds the Nt, a winding detection signal is immediately imparted to a control circuit 11.
